# OneDay vs Countdown

The clearest difference is in-app purchases: Countdown at none against OneDay's 1. Countdown also leads on update cadence (every 3 months vs every 8 months) and iOS requirement (13.0 vs 16.0). On price, ads and device support there is nothing between them.

Both are free to download. OneDay sells 1 one-off in-app purchase. Countdown asks for nothing beyond the download.

OneDay ships an update every 8 months, Countdown every 3 months. The most recent releases landed on October 7, 2026 and September 25, 2026 respectively.
